We just finished celebrating National Engineer’s Week 2013 here at EWI. After all, our engineers are our products, and their knowledge and abilities are great reasons to celebrate. Our Staff Association did a great job of putting together a fun week of activities to celebrate our engineers. On Monday we had Chris Cakes come to […]
Read MoreThe Department of Energy has a substantial fleet of nuclear facilities that have reached their end of life or are projected to be at end of life in the near future. Many of these facilities are contaminated with radionuclides, asbestos, lead based paint, or other forms of contamination. These facilities need to be deactivated and […]
Read MoreHere’s a test to see if you’re a Common Man… If I asked you (95% of the people reading this blog) to describe what welding is, I’m guessing you would describe one of two things: Arcs and/or Sparks. When I started here at EWI as CFO, I pictured either a guy flipping down his welding […]
Read MoreMore and more, robotic welding is becoming a viable option for use in heavy fabrication. The sophistication and capacity of modern robot systems is suitable for large structures which require multi-pass welds. Processes used for heavy fabrication such as preheating, gas metal arc welding (GMAW), flux cored arc welding (FCAW), tandem gas metal arc welding […]
Read MoreSo I’m not what you would call a handy person around the house and I generally pass on home projects unless forced to act. In fact I pretty much epitomize the quote “If a man says he will fix it he will. There is no need to remind him every six months about it.” I […]
Read MoreGas metal arc welding (GMAW) and gas tungsten arc welding (GTAW) are both regularly used for welding aluminum. GTAW is a slow process when compared to GMAW and GMAW is typically used when extremely high weld quality (with respect to porosity) is not required. GMAW works well for welding aluminum in structural, automotive, or thick […]
Read MoreWell folks, Movember is upon us. Some of you call this no-shave November and use it as an excuse to grow a beard or a goatee or something like that. It is officially called Movember and growing a sweet moustache is the proper way to raise awareness and money for men’s health issues. Prostate cancer […]
Read MoreI’m not sure if “politicing” is used appropriately as a verb (kind of like “efforting”), but it seems accurate for what is happening these days around the deficit. On the positive side, the media is continuing to publicize the deficit as the major issue for the candidates to address. But in this case, “address” is […]
Read MoreSubmerged arc welding (SAW) is a high deposition rate process when compared to gas metal arc welding (GMAW) or gas tungsten arc welding (GTAW). Certain applications such as large flat panels, girth welds in pipe, or spiral pipe mills can benefit from techniques used to increase the deposition rate, and consequently, the productivity of the […]
Read MorePlasma arc welding (PAW) is very similar to gas tungsten arc welding (GTAW). If you look at the schematic shown in Figure 1 you can see that the arc in PAW is created between a non-consumable tungsten electrode and is constricted by passing through an orifice. This provides a more columnar arc with a higher […]
